FRICTION GRIP CAP FOR CONTAINERS.

Application filed August 18, 1925. Serial No. 50,956.

Our invention relates to improvements in caps for containers, and it consists in the novel features hereinafter described.

= One of the objects of our invention is to provide an improved cap for containers to be securely kept in place on the neck of the container and to be readily placed in position thereon.

Another object of our invention is to have said cap with an integral lower edge or skirt, the gripping device of the cap being located in a part thereof intermediate of the crown or top and said skirt.

A further object of our invention is to have the gripping device of our cap for containers agreeable to the eye and artistic in appearance.

A still further object of our invention is to have our friction grip cap for containers simple, durable and inexpensive.

Other objects and advantages will hereinafter appear.

We attain these objects by the friction grip cap for containers, illustrated in the accompanying drawings, or by any mechanical equivalent or obvious modification of the same.

In the drawings Fig- 1 is a horizontal section on the line 11 of Fig. 2, showing also the neck of the container.

Fig. 2 is a vertical section on the line 2-2 of Fig. 1, omitting the neck of the container.

Fig- 3 is a vertical section on the line 3-3 of Fig. 1, also omitting the neck of the container.

Figs. 4, 5, 6. and 8 are fragmentary details of modifications of our friction grip cap for containers, showing different ways of forming the gripping device by slitting the metal walls of the cap.

Fig. 7 is a horizontal section on the line 7-7 of Fig. 8, showing also the neck'of the container.

Similar numerals refer to similar parts throughout the several views.

11 designates the wall of a metal cap of a container, which cap may have therein an enlargement or skirt 12 at the lower end thereof, as shown in Figs. 1, 2 and 3, if de sired; the said skirt may also be dispensed with, if desired.

13 is the crown or top of the cap, and i may be of any usual design.

The gripping device of our cap is formed by slitting the wall 11 at a part thereof intermediate of said crown 13 and skirt 12; theslits may be situated as-at 14. and 15 in Figs. 2 and 3 or l l and 15 in Fig. 8, and may consist each of a horizontal cut 14 or lt and a vertical cut 15 or 15 the angular strips of metal 16 or 16 formed by said slits 14: and 15, or 14 and 15*, may then be bent inwardly, as shown in Figs. 1 and 7; the angle or deflection of the bends of the strips 16 is shown as exaggerated in Fig. 1, for the sake of clearness.

Other forms of slits for our cap are shown at 24 and 25 in Fig. 4-, with the strip 26 resulting therefrom, at 34; in Fig. 5, with the strip 36 formed thereby, and at 4.4 in Fig. 6, with the strip 46 formed thereby. The strips 16 in Fig. 8 differ only in their relative positions from the strips 16 in Figs. 2 and 3.

It is evident that the strips of the gripping device of our cap for containers may have a wide variety of forms, all of them having the feature in common of being cut by slitting from a part of the wall of the cap intermediate of its crown and skirt or lower edge.

We also prefer to have thegripping strips in pairs symmetrically arranged, as shown in the drawings.

When the cap is placed on the neck 17 of the container the latter causes'the gripping strips to be sprung back almost into their original position in the wall of the cap, as shown in Fig. 7, where the space between the neck 17 of the container and the wall 11 of the cap is small, and it may be smaller yet in practice.

In Fig. 1 the space between the neck 17 of the container and the wall 11 of the cap is exaggerated, to illustrate the bend of the gripping strips.

The number of gripping strips may be either larger or smaller than shown in the drawings.

Many other changes may be made in the details of our cap for containers without departing from the main scope of our invention and parts of our invention may be used without other parts.

WVe claim as our invention and desire to secure by Letters Patent:

1. A friction grip cap for containers comprising a crown, a lower part and a part intermediate of said crown and said lower larger than the neck of said container, gripping strips slit from said intermediate part transversely to the periphery thereof and initially bent inwardly to a position enclosing a narrower space than the neck of the container, said strips being arranged in pairs, the strips in each pair being symmetrically disposed to each other, said strips to be sprung outwardly by said neck, thereby causing said neck to be gripped by said strips, and said cap to be retained by friction on said neck. I

2. In a friction grip cap for containers comprising a crown,'a :lower part and an intermediate part, L-shaped gripping strips slit from said intermediate part transversely to the periphery thereof and initially bent inwardly to a position enclosing a narrower space than the neck of the container, said strips being arranged in pairs, the strips in each pair being symmetrically disposed to each other, said strips to be sprung outwardly by said neck, thereby causing said neck to be gripped by said strips and said cap to be retained by friction on said neck.

3. In a friction grip cap for containers, comprising a crown, a lower part and an intermediate part, gripping strips formed by L-shaped slits from said intermediate part, onev side of each of said L-slits being vertical and the other side horizontal, and said slits being arranged in pairs, the slits in each pair being symmetrically disposed to each other.
